Mechanical behavior of composite parts joined through different processes

Abstract

Abstract In this research, composite parts joined according to different joining methods such as single-lap and double-lap embedded adhesive subjected to tensile load were analyzed via the 3-D finite element method (FEM). The study differed from other studies in terms of joining techniques used and the specified parameter and model design. This study aims to emphasize the advantages of joining techniques in terms of aesthetically and joining methods over each other. In the analysis, composite parts carbon/epoxy (T 700) at varied fiber orientation angles and adhesive DP 410 were used. The models for numerical analyses were created in an ANSYS 14.5 software package. Finite element analysis (FEA) was successful in predicting failure loads. Stress in the x, y, z directions, shear stress and von-Mises stress on the adhesive were obtained at the time of failure for predetermined parameters. As a result, the effects of orientation angles, overlap lengths, adhesive layer and bonding methods were investigated. The maximum effect parameter and joining technique was determined for the composite parts joined through varied joining methods.
